Description

Technical Field

[0001] The utility model belongs to the technical field of flame retardancy detection, and in particular relates to a flame retardancy detection device for building materials. Background Art

[0002] During construction and decoration, flexible building materials such as electrical wires and building material sheaths are used. These building materials need to allow current to pass through the cores to transmit electrical energy. To ensure the stability and reliability of the current passage, these building materials need to be tested for flame retardancy before use.

[0003] The Chinese patent with publication number CN215768338U discloses a device for detecting the flame retardant and fire resistant properties of electric wires. This solution sets up a linkage assembly. When the wire to be tested is heated at high temperature in the box, it can rotate so that the wire to be tested is heated more evenly, thereby improving the detection effect. It is an efficient embodiment of the equipment for detecting the flame retardant and fire resistant properties of the wire to be tested.

[0004] However, in actual use, when applied to the inspection of the above-mentioned wires, building material sheaths and other building materials, since the fixed module is installed on a turntable, and the turntable can only rotate relative to the box body but cannot move, the distance between the fixed modules on both sides cannot be adjusted, that is, the device cannot clamp and fix building materials of different lengths, resulting in a small scope of application of the device, which is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a flame retardant detection device for building materials, so as to solve the problem of small application scope of the prior art mentioned above.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flame retardant detection device for building materials, comprising

[0007] The box body has a blower and an exhaust assembly installed on the top of the box body, and a temperature sensor is arranged inside the box body;

[0008] A flame spray assembly, wherein the flame spray assembly is installed in the box;

[0009] The adjusting mechanism includes a wheel, a bidirectional screw and two nut seats. An adjusting groove is provided on the inner wall of the box body. The bidirectional screw is rotatably installed in the adjusting groove. One end of the bidirectional screw extends outside the box body and is fixed to the wheel. The two nut seats are threadedly sleeved on the bidirectional screw and slidably fit in the adjusting groove.

[0010] The clamping mechanism comprises two clamping units which are respectively arranged on the nut seats on both sides.

[0011] The principle and effect of this technical solution:

[0012] 1. Adjust the distance between the two clamping units through the adjustment mechanism so that the clamping units can clamp building materials of different lengths, then close the protective door of the box, and then operate the flame spray assembly to heat the clamped building materials, observe the temperature changes of the temperature sensor and the state of the building materials, so as to obtain the heat resistance of the building materials, and observe the combustion conditions of the building materials to obtain the flame retardant data of the building materials, and discharge the exhaust gas in the box through the exhaust assembly according to the air pressure inside the box at the blower position.

[0013] 2. The bidirectional screw can be rotated by rotating the wheel, so that the two nut seats can move in the adjustment groove, and then the nut seats on both sides can synchronously drive the two clamping units to move closer or farther away from each other, thereby playing the function of distance adjustment, so that the position of the clamping unit can be adjusted according to the length of the building material, thereby improving the application range of the device.

[0014] The utility model is further configured as follows: the clamping unit includes a connecting plate, a fixed collar, a rotating sleeve, a driving assembly and two clamping assemblies, one end of the connecting plate is connected to the nut seat, the other end of the connecting plate is connected to the outer wall of the fixed collar, the rotating sleeve is rotatably installed in the fixed collar, the driving assembly is installed on the connecting plate and is used to drive the rotating sleeve to rotate, the two clamping assemblies are symmetrically arranged on the rotating sleeve, the clamping assembly includes a clamping bolt, a limiting rod and a clamping block, the clamping bolt is threadedly inserted into the side wall of the rotating sleeve, and the end of the clamping bolt extends into the rotating sleeve and is rotatably connected to the clamping block, one end of the limiting rod is slidably inserted into the side wall of the rotating sleeve, and the other end of the limiting rod is connected to the clamping block.

[0015] The principle and effect of the technical solution are as follows: the fixing sleeve and the nut seat are connected as a whole through the connecting plate, so that the nut seat can drive the fixing sleeve to adjust the position, and the driving assembly drives the rotating sleeve, so that the clamping assembly can rotate with the rotation of the rotating sleeve, thereby driving the building material to rotate, so that the building material is heated more evenly and the detection effect is more accurate, and the rotating sleeve is rotatably connected to the fixing sleeve, so that the position of the rotating sleeve can also change with the change of the position of the nut seat; because the clamping bolt is threadedly connected to the rotating sleeve, the end of the clamping bolt can be moved close to or away from the center of the rotating sleeve by rotating the clamping bolt, so that the clamping block is moved close to or away from the building material, and the distance between the two clamping blocks is adjusted so that the device can clamp building materials of different thicknesses, and the limit rod restricts the driving rod so that the driving rod will not rotate with the rotation of the clamping bolt, so that when the clamping bolt clamps the building material, the position does not need to be adjusted, and the operation is simpler.

[0016] The utility model is further configured that: the side wall of the clamping block away from the clamping bolt has an arc surface.

[0017] The principle and effect of the technical solution: the setting of the arc surface enables the clamping block to have more clamping points or clamping surfaces when clamping building materials, thereby being able to play a more stable clamping function for the building materials.

[0018] The utility model is further configured as follows: a driving assembly includes a driving motor, a rotating shaft, a driving gear, a driven gear and a protective plate, the driving motor is mounted on the side wall of the connecting plate, the protective plate is fixed on the nut seat, the rotating shaft is rotatably mounted on the protective plate, and one end of the rotating shaft is connected to the rotating end of the driving motor, the other end of the rotating shaft is connected to the driving gear, the driven gear is mounted on the rotating sleeve, and the driving gear is meshed with the driven gear.

[0019] The principle and effect of this technical solution is as follows: the driving motor drives the rotating shaft to rotate, thereby causing the rotating shaft to drive the driving gear to rotate. Since the driven gear is meshed with the driving gear, the driving gear drives the driven gear to rotate, thereby driving the rotating sleeve to rotate, and causing the building materials clamped by the clamping assembly to rotate accordingly, so that the building materials are heated evenly. Moreover, by setting the protective plate, the lateral pressure of the rotating shaft can be borne, thereby avoiding damage to the driving motor.

[0020] The utility model is further configured as follows: the outer shape of the connecting plate is an inverted U-shape, two fixing collars are provided and are respectively connected to the two side wall ends on the same side of the connecting plate, and the clamping bolt is located between the two fixing collars.

[0021] The principle and effect of this technical solution: the setting of the two fixing rings makes the rotation of the rotating sleeve in the fixing ring more stable and reliable. At the same time, the clamping bolts are given space through the gaps between the side walls of the connecting plates and the gaps between the fixing rings, so that the size of the rotating sleeve is smaller, and the clamping bolts are rotated between the fixing rings, so that a certain limiting effect can be exerted on the rotating sleeve.

[0022] The utility model is further configured as follows: the exhaust assembly comprises an exhaust fan and a filter box, the filter box is installed on the top of the box body, and the exhaust fan is installed on the top of the filter box.

[0023] The principle and effect of this technical solution: low pressure is formed by the rotation of the exhaust fan, so that the gas in the box flows toward the exhaust fan, passes through the filter box, and the harmful substances produced by the combustion of building materials are filtered and adsorbed by the filter material (such as activated carbon, etc.) in the filter box, so that the gas discharged by the device will not harm the environment.

[0024] The utility model is further configured to include a supporting plate, which is slidably inserted into the bottom of the inner side of the box body.

[0025] The principle and effect of this technical solution: the sliding insert tray can block and collect dripping materials when building materials are burning, thereby preventing the bottom of the box from being attached by dripping materials, and then the tray can be easily cleaned by sliding out, making it easier for users to maintain the cleanliness of the device.
